std::getline C++ Strings library std::basic_string Defined in header<string> template<classCharT,classTraits,classAllocator> std::basic_istream<CharT, Traits>& getline(std::basic_istream<CharT, Traits>&input, std::basic_string<CharT, Traits, Allocator>&str, CharT delim); ...
3,4) 同getline(input, str, input.widen('\n')),即默认分隔符是换行符。参数input - 获取数据来源的流 str - 放置数据的目标字符串 delim - 分隔字符 返回值input 注解消耗空白符分隔的输入(例如 int n; std::cin >> n;)时,任何后随的空白符,包括换行符都会被留在流中。然后当切换到面向行的...
basic_istream&getline(char_type*s,std::streamsizecount, char_type delim); (2) 从流提取字符,直至行尾或指定的分隔符delim。 重载(1)等价于getline(s, count, widen('\n'))。 表现为无格式输入函数(UnformattedInputFunction)。构造并检查 sentry 对象后,从*this提取字符并将它们存储于以s指向其首元素的...
basic_istream& getline( char_type* s, std::streamsize count, char_type delim ); (2) Extracts characters from stream until end of line or the specified delimiter delim. The first overload is equivalent to getline(s, count, widen('\n')). ...
a function call or an overloaded operator expression of lvalue reference return type, such as std::getline(std::cin, str), std::cout << 1, str1 = str2, or ++it; (运算符重载并且返回值是引用的方法) a = b, a += b, a %= b, and all other built-in assignment and compound assig...
1) 在作用域(scope)内的、无论什么类型的变量名或者函数名。比如,std::cin或者std::endl。即使这个变量的类型是右值引用,由它的名字组成的表达式也是个左值表达式。 2) 把左值引用作为返回的函数或者重载操作符。 比如,std::getline(std::cin,str),std::cout << 1, str1 = str2, 或 ++it; ...
